Product Profile of Hand Driven Generator Type Insulation Testers
Yokins Instruments manufactures Hand Driven Generator Type Insulation Testers. Yokins Instruments is an ISO 9001:2000 certified company. Yokins Instruments supplies Analog and Digital Electrical; measuring panel meters such as Power meters, Wattmeters, Voltmeters, Ammeters, etc. The Hand Driven Generator Type Insulation Testers are compact, portable self-contained instrument which is used for direct reading of insulation resistance of electrical installations and apparatus. The Insulation tester is composed of a hand driven A.C. Generator and a high sensitivity cross-coil Indicator.
Key Features of Hand Driven Generator Type Insulation Testers
- Cross coil indicator: the indicating movement is of the cross coil ratio type and is designed so that voltage fluctuation caused by irregular cranking have no influence on the results of measurement.
- Infinity adjustment: this has been provided in the instrument.
- Silent generator: the ac magnet hand generator drive is extremely smooth and silent. There are no carbon brushes and commutators, to be replaced as in dc generators.
- Quick response: The quick response saves the time and extends the life of the generator.
- Response Time: Less than 3 seconds, when a resistance, the value of which corresponds to the central scale mark is suddenly inserted between measuring terminals
- Limits Of Error: The insulation resistance measurement is accurate to within [+/-]5% of the indicated value over the effective range and within [+/-]10% of the indicated value at the scale mark for the rest of the ranges in conformity with I.S.2992-1980
- Tolerance Of Voltage Across Measuring Terminals :Within [+/-]10% of the rated voltage for scale mark of infinity and more than 90% of the rated voltage for the central scale mark in confirmity with I.S.2992-1980.
- Rotations Speed of Handling: 160 R.P.M.
- Central Scale Mark: 1/50th of rated resistance value.
- Insulation Resistance: More than 50 mega ohms between the electrical circuits and the case, when measured by applying 500V DC
- Di-Electric Strength: Withstands 1 minute application of 2000 volts AC [rms] between the electrical circuits and the case
- Weight: Approximately 3Kg. For model Y1-M1 and Y1-M2
- Optional Accessories: 1 Carrying case 2. Test Leads.
- Dimension: For Model Y1-M1 & Y1-M2: 170X100X110mm [approx].
